COUPLING.

I as are used for connecting flexible hose of embodiment of the invention.

train-pipes, this application being adivision of my previous application No. 442,242 of July 6, 1908.

The accompanying drawings illustrate an Figure 1 is anelevation of the train pipe and coupled hose with two adjacent cars; Fig. 2 is a similar elevation of a pair of couplers in the coupled position, one of them being partly in section; Fig. 3 is a plan of one of the couplers of Fig. 2.

Referring to the-embodiment of the invention illustrat d, the hoseAcarries on its lower end a coupler B of any usual or suitable type adapted to intercouple with the cou ler on the adjacent car by hooking an arm over a flanged projection D on the mating coupler.

Eachcoupler has a pair of lugs E on theupper part of its neck, between which runs a horizontal pin F forming the pivot of a stud G, upon the'upper end of which is pivoted an L-shaped arm H preferably provided with a handle J and having its outer portion adapted to extencP-over the side of the coupler so as to overlie the arm C of the mating coupler, as shown at the left in Fig. 2, and to lock this arm down in the coupled position. The pivotal movement of the locking member H may be limited by a pair of studs M and N. on the top of the coupler.

For holding the lockinq member H in either-its locked or its unloclred position, and for providing at the same time means for .re during the strain on the hose in automatic u ncoupling, .I )IOVldG a lever O, pivoted also on the stud (i and having its lower end P overlying the locking member H; and I exert a constantupward pull upon the rear member of the lever 0 so as to press the forward member P and the locking member H down on the top of the coupler with a suiticient frictional force to prevent accidental movement of the locking member. The pull on the arm 0 is preferably effectedby means of a chain Q fastened to the rear end of the lever and running up to a suitable point of attachment. A .convenientpoint is a lug R on the sleeve of the upper end of the hose.

. With this position of attachment of the upper end of the chain, it is clear that in an au-' ,tomatic uncoupling operation as'the hose A tends to straighten out, there is also a tendency to shorten the chain. A spring S, however, is preferably interposed in the chain so as to take 11 the difference in length occasioned unc er the conditions stated, and to still exert some pulling strain effect. But as soon as the uncoupling action commences, the pull of the chain becomes more and more nearly at right angles to the longitudinal axis of the coupler, conse- -upon the couplers, and to that extent to requently its pulling effect upon thec oupler is greater. The chain may be substituted by a rod or any other connection having the de' sired supporting or pulling effect. What I claim is:-

1. A hose'coupler having a locking mom ber adapted to be moved to the looking or to the unlocking position, and chain-operated meansfor holding it impositively in either position to which ll'rlS moved.

2. A hose coupler havinga locking member adapted to be moved to the looking or to the unlocking position, and a chain-operated lever bearing on said locking member to hold it impositively in either position.

3. A hose coupler having a pivoted locking I member H and a pivoted holding lever 0 the. lower end of which engages said locking memher to hold it in ranged to exert a ifting force on the upper end of said lever.

In witness whereof, I have hereunto si ned my name in the presence of two subscri ing witnesses.
